“…This phenomenon was possible partly for the different pH values among treatments and the pH value of the Non-R treatment was the lowest (Table 2). Additionally, phenolic compounds were the main autotoxicity substance in rhizosphere soil of many plants and it would influence the growth of plants; thus, the utilization of phenolic compounds was higher in Non-R treatment than the rhizosphere soil [63,64]. The application of L1 significantly improved the utilization of the six main carbon sources (carbohydrate, carboxylic acid, phenolic compounds, amino acid, polymer, and amine) by 76.6, 40.1, 22.4, 81.6, 29.7, and 2.9% than the NPK treatment, respectively.…”

Abstract:Organic fertilizers are generally thought to be an effective way to sustain soil fertility and plant growth. To promote the productivity of chrysanthemum, five sources of liquid organic fertilizers (L1-L5), as well as a chemical fertilizer, were applied at an early stage of the growth cycle to investigate their effects on plant growth. In the short-term pot experiment, the liquid organic fertilizers significantly promoted root and aboveground growth by 10.2-77.8% and 10.7-33.3%, respectively, compared with the chemical fertilizer. The order of growth promotion was: L1 (shrimp extracts) > L2 (plant decomposition) > L4 (seaweed extracts)/L5 (fish extracts) > L3 (vermicompost). Morphological and chemical analyses indicated that, compared with other organic fertilizers, the treatment with shrimp extract (L1) produced the greatest increases in root dry weight, total length, surface area, volume, tips, and thick root length, respectively. Furthermore, the shrimp extract treatment significantly increased the nutrient contents and altered the soil's functional microbial community at the rhizospheric level compared with the chemical fertilizer treatment. Thus, the shrimp extract liquid organic fertilizer could be part of an effective alternative to chemical fertilization during the early stage of chrysanthemum growth.

“…The autotoxicity of phthalic acid, cinnamic acid, and its derivatives in root decomposed products or exudates of cuceumbers, and peas has been reported,phthalicacid, p-hydroxybenzoicacid, isobutyricacid, and glutaric acid were identified from the phytotoxic acidic fractionof the root exudates of soybean (Kong & Xu, 2003;Williamoson & Richardson, 1988;Xiao et al, 2014). Coumaric acid, long chain fatty acids and phenolic substances with the low content, were also identified in decomposed maize straw products, and the allelopathy of some compounds also has been reported (Lin et al, 2002;Asaduzzaman & Asao, 2012;Röhrig et al, 2013;Wang et al, 2014). Nevertheless, this is the first report of the presence of cinnamic acid phthalicacid, p-hydroxybenzoicacid, isobutyricacid, and glutaric acid in Adzuki bean extracts from plant extract and rhizospheresoil of Adzuki bean.…”

The soil sickness of Adzuki bean [Vigna angularis (Willd.) Ohwi & H. Ohashi] have been getting attention seriously under a continuously mono-cropping management-system in China. To investigate the allelopathy of rhizosphere soil and plant of Adzuki bean, culture dish and pot experiments were conducted. The compounds in the products were identified by High Performance Liquid Chromatography (HPLC).The aqueous extracts from rhizospheric soil and whole plant inhibited seed index (seed germination and seed potential) and plant growth under different degrees, and it showed concentration gradient effect on the inhibition of seed germination. Inhibition was stronger with increasment in extract concentration with the highest effect at 0.16 parts aqueous extract to 1 parts deionized water (0.16g·mL -1 ). The impact on growth varied among aqueous extracts from rhizospheric soil and the whole plant. Five phenolic compounds, cinnamic, phthalic, p-hydroxybenzoic, and isobutyricand glutaric acids, were detected from the rhizosphere soil and plant extract of Adzuki bean by HPLC method. Cinnamic, phthalic, and p-hydroxybenzoicacids were higher than that of the other phenolic acids. This result suggests that autotoxicity effects of phenolics on Adzuki bean probably happen in continuous mono-cropping systems.

“…In agro ecosystem legume crops release a great number of allelochemicals. Assaduzzaman and Asao [25] identified benzoic, salicylic, and malonic acidsin the root exudates of P. vulgaris and lactic, benzoic, p-hydroxybenzoic, vanillic, adipic, succinic, malic, glycolic, and p-hydroxyphenylacetic acids in V. faba. In another study, pisatin in the P. sativum shoot was identified by Kato-Noguchi [13].…”

“…Asao et al [24] mentioned sweet pea (Lathyrusoduratus L.) shoot fresh weight and dry weight greatly reduced by the release of autotoxic malonic acid, benzoic acids p-hydrobenzoic acids and vanillic acids from its roots into the rhizosphere. Assaduzzaman and Asao [25] investigated the autotoxicity of P. sativum, P. vulgaris, and V. faba in hydroponics either with or without activated charcoal (AC) addition. Growth and yield of the three beans were significantly reduced when grown in the culture solution without AC addition.…”

Plant releases many bioactive chemicals from its various parts such as leaves, stem, root and sometimes decomposed body through different mechanism into its surrounding environment. These bioactive chemicals are often termed as allelochemicals because they interact with the surrounding environment. This interaction is either positive or negative. Effects of allelochemicals to the agricultural and biological ecosystem are well documented. In leguminosae family many species are involved in releasing of allelochemicals. Many researchers found that this allelochemicals have both positive and detrimental effects on the successive legume crops. Legume monoculture is common in many parts of the world where they cause a numbers of ecological and economic problems such as decline in crop yield due to soil sickness, regeneration failure and replant problem. These negative effects of allelochemicals open a great concern on allelopathy research. This article reviews the adverse effects of allelochemicals, their extraction and isolation, mechanism inside the plant body. These all are done to find out the possible selection methods of succeeding crops to avoid the allelopathic effects in the next crop of a monoculture farm field. The main purpose of this article is to highlight the adverse allelopathic effects of legume crops to provide ways for sustainable development in agro-ecosystem.
